The physico-chemical characteristics of thin poly-(orth o-phenylenediamine) (PPD) films, obtained by electrochemical oxidation of the relevant monomer, are investigated using electrochemical, morpholog-ical and spectroscopic techniques.

Abstract
The physico-chemical characteristics of thin poly-(orth o-phenylenediamine) (PPD) films, obtained by electrochemical oxidation of the relevant monomer, are investigated using electrochemical, morpholog-ical and spectroscopic techniques. In particular, cyclic voltammetry and electroche mical impedance spec-troscopy (EIS) techniques are used to collect information concerning the redox, conductivity and double layer capacitance properties of the PPD film. AFM imaging and Raman spectroscopy results are exploited to characterize the film structure. In this respect, Raman spectra of two possible PPD oligomers are cal-culated at the B3LYP/6-311G level of the theory.
